5 Gastric Sleeve Myths Debunked: Separating Fact from Fiction


The weight loss journey can be a challenging one, and for those struggling with obesity, it can feel like an uphill battle. Despite the various diet and exercise plans available, some individuals may still struggle to lose weight effectively. As a result, many people turn to surgical options such as gastric sleeve surgery to help with their weight loss goals. However, there are several myths and misconceptions surrounding gastric sleeve surgery that can deter individuals from considering it as a viable option. In this article, we will debunk some of the most common myths associated with gastric sleeve surgery and provide information to support the procedure’s effectiveness.

Myth 1: Gastric Sleeve Surgery is Dangerous

One of the most common myths surrounding gastric sleeve surgery is that it is a dangerous procedure. While all surgeries come with some level of risk, gastric sleeve surgery is considered a safe and effective weight loss treatment option. According to the American Society for Metabolic and Bariatric Surgery, the mortality rate for gastric sleeve surgery is less than 1%. With proper pre-and post-operative care, the risk of complications is minimized.

Myth 2: Gastric Sleeve Surgery is Only for the Morbidly Obese

Another myth surrounding gastric sleeve surgery is that it is only suitable for those who are morbidly obese. This misconception stems from the fact that gastric sleeve surgery was initially designed for individuals with a BMI (Body Mass Index) of 40 or higher. However, the eligibility criteria for gastric sleeve in St. Louis have since expanded to include individuals with a BMI of 30 or higher who have obesity-related health conditions such as diabetes or high blood pressure.

Myth 3: Gastric Sleeve Surgery is a Quick Fix

Some people view gastric sleeve surgery as an easy way out and believe that it provides instant weight loss results. However, this is not the case. Gastric sleeve surgery is a tool to help individuals achieve their weight loss goals, but it still requires commitment and dedication to a healthy lifestyle. Patients must follow a strict diet and exercise plan post-surgery to maintain long-term weight loss.

Myth 4: Gastric Sleeve Surgery is Reversible

Contrary to popular belief, gastric sleeve surgery is not reversible. During the procedure, a large portion of the stomach is removed, making it impossible to reverse the surgery. Therefore, it is crucial for individuals considering this treatment option to thoroughly research and understand the procedure before deciding.

Myth 5: Gastric Sleeve Surgery Causes Nutritional Deficiencies

Another common myth is that gastric sleeve surgery leads to nutritional deficiencies. While it is essential for gastric sleeve patients to follow a specific diet and take supplements post-surgery, these measures are in place to prevent any potential nutrient deficiencies. With proper guidance from healthcare professionals, patients can maintain their nutritional needs while losing weight. You may also ask your doctor about what happens if you eat solid food after gastric sleeve, as they will provide you with the necessary information.


Gastric sleeve surgery has proven to be a safe and effective weight loss treatment option for many individuals struggling with obesity. By debunking these myths and providing information, we hope to encourage those considering this procedure to make an informed decision. As with any major decision, it is crucial to consult with a healthcare professional and thoroughly research the procedure before proceeding.
